One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?
Insects on both continents have similar feeding habits.
The rates of sedimentary rock formation are similar.
The ancient atmosphere in both places was identical.
Fossil remains of the same land-dwelling animal were found on each continent.
An illustration of how a convection current creates a wind, called a sea breeze, is provided. Which of the following best explains what creates this convection current?
Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.
During the day, the Sun’s energy heats up the land faster, which makes the air above it warmer.
The rotation of Earth makes the air above it rotate, but not the same over land and water.
During the day, Earth’s gravity creates a high pressure area over both the land and water.
The star, Spica, is highlighted in the Hertzsprung-Russell diagram. According to the H-R diagram, which of the following correctly describes the star, Spica? It is a -

blue, bright main sequence star.
One piece of evidence for Plate Tectonic Theory is seafloor spreading. The diagram provided shows the pattern of rock on either side of the Mid-Atlantic Ridge. The evidence that indicates that plates are moving apart at this location is that, as one looks at the rocks on either side, one sees that -
rocks are older the farther they are from the center
there is a thickening of the crust where the sides meet
rock types on one side are very different from the other
one rock layer melts as it moves under the other side
A steep slope, one that would be difficult to climb, can be recognized on a topographic map by looking for contour lines that -
have large numbers
are spaced closely together
are thicker than other lines
form v-shaped points
